Abstract
A system, method, and computer program for producing a visualization format from CAD data comprising producing a BREP model for visualization, wherein said BREP model has a topology component and a geometry component; removing a plurality of redundant control points from said geometry component; normalizing a plurality of knot vectors and a plurality of weight components from said geometry component; recognizing an analytic geometry from said geometry component; recognizing a plurality of equivalents from said geometry component; and converting said analytic geometry to said light model representation, and appropriate means and computer-readable instructions.
